FRESMAK ARNOLD CLASSIC PNEUMO-HYDRAULIC
The first high-pressure vice, launched by Fresmak in 1967. Includes pneumatic spindle designed for process automation.
Characteristics
- Designed for process automation and robotisation.
- Equipped with a high-pressure, single-acting pneumo-hydraulic multiplier which uses a compressed air supply at 6 bars of pressure.
- Clamping force is regulated by inlet air pressure (see manual).
- Automatic forward and reverse travel of 3 mm.
- The control of the vice can be manual (by means of the valve assembly that is sent with the clamp), by means of a pedal located outside the machine, or it can be controlled by means of the CNC using a solenoid valve.
- Split option available upon request.
+ ARNOLD CLASSIC General Characteristics (Read more)
- Movable spindle: the total length of the vice is determined by the length of the workpiece to be clamped.
- Accuracy of 0.01 mm in clamping repeatability.
- Monoblock design avoids deformations caused by high pressure and provides great robustness.
- The force applied by the high-pressure spindle is transmitted to the workpiece through the centre of the clamping jaw, utilising 100% of that force.
- Large aperture, up to 375 mm or 845 mm if the workpiece body is in two parts.
- 25/40/50/80 kN clamping force depending on size.
- The ARNOLD CLASSIC spindles can be used independently from the vice as a clamping element in a workholding set up.
- Available in 3 versions: standard, straight, and straight in two parts.
- Optional swivel base
- Optional pressure regulator.
- Available sizes (width):
- 125 / 160 / 200 mm
Clamping Technology
Workholding - Tips for use
- The air must be filtered (dry air).
- If using a pedal control, the valve assembly supplied with the vice must be placed between the compressor and the pedal, not between the pedal and the vice.
Workholding - Required elements
- Connection hose from compressor to vice.
- Inlet air filter, pressure gauge, and lubricator assembly.

Special jaws
Fixed nut: supported on a past to push. The spindle travels with the mouth moving.
Movable jaw guided on the outside of the slides.
The movable jaw can be easily removed to facilitate the maintenance of the VICE.
